get highest value in dictionary python code example

Example 1: python how to find the highest number in a dictionary

a_dictionary = {"a": 1, "b": 2, "c": 3}

max_key = max(a_dictionary, key=a_dictionary.get)
get key with max value


print(max_key)

Example 2: max of a dict

dic={0: 1.4984074067880424, 1: 1.0984074067880423, 2: 1.8984074067880425, 3: 2.2984074067880425, 4: 2.2984074067880425}
max_value = max(dic.values())  # maximum value
max_keys = [k for k, v in dic.items() if v == max_value] # getting all keys containing the `maximum`

print(max_value, max_keys)

Example 3: python max key dictionary key getter

from operator import itemgetter

items = [
    {'a': 1, 'b': 99},
    {'a': 2, 'b': 88},
    {'a': 3, 'b': 77},
]

print(max(items, key=itemgetter('a')))
print(max(items, key=itemgetter('b')))

Example 4: find the highest 3 values in a dictionary.

from collections import Counter
# Initial Dictionary
my_dict = {'t': 3, 'u': 4, 't': 6, 'o': 5, 'r': 21}
k = Counter(my_dict)
# Finding 3 highest values
high = k.most_common(3)
print("Dictionary with 3 highest values:")
print("Keys: Values")
for i in high:
   print(i[0]," :",i[1]," ")

Example 5: find the highest 3 values in a dictionary.

>>> sorted(my_dict, key=my_dict.get, reverse=True)[:3]
['K', 'B', 'A']
